Key findings
A focused interpretation of the evidence, relationships and observation history that matter most.
Analysis takeaway
Elevated engine detections. Related indicators in this report: 17. Review the supporting evidence before taking action.
Detection signal
Malicious. Engine detections are elevated at 33%.
Confidence signal
VirusSign reports 100% confidence. Review this alongside engine detections and relationship evidence.
Threat context
Classification includes type trojan and family mirai.
Relationship context
17 related indicators are shown across 4 relationship group(s). Additional relationship intelligence is available through API and data access.
Observation timeline
18 timestamped observations are arranged from 2022-01-13 to 2026-11-12. These are observation or metadata times, not execution order.
Why this verdict
Review the reported detections, analysis confidence and supporting context.
Engine detections are elevated in this report. Review the reported confidence, classification and relationships alongside them.
Reported engine detection rate, not the probability that this indicator is malicious.
VirusSign analysis confidence; separate from detection rate and actor-association confidence.
4 relationship group(s) provide pivot and infrastructure context.
Classification context: type trojan, family mirai.
Last seen 1 day ago.
Signals reflect the intelligence returned in this report. Missing values mean not reported, not zero. Related indicators are investigation leads, not proof of shared malicious activity.
